I got the quest from Relstaroth to create Imbued Mithril Bars (Lairshaping Mastery Part 5). After near 2 hours of work I had aquired enough to make more than enough of them.
Only to get the message "The equipped tool is not of high enough quality to work with Shining Essence Orb". First I thought the biped smelter might be a problem. But as even a t6 dragon forge shows the same message I came to realize, that I cannot craft these freaking imbued bars at all with my ability Lairshaping III, which is the _only_ one I have!
Relstaroth mustn't give me a quest if I don't even meet the requirements for that quest aka don't have the ability Lairshaping IV. It made me upset for the wasted time and now the wasted space I found so I dont have to delete the resources which filled my vault, disk and inventory otherwise.
I'm level 55 lairshaper, level 100 crafter btw.
as you can see I meet any requirement
